This study explores the theoretical foundation behind the application of surface-enhanced Raman spectroscopy (SERS) for neonicotinoid quantification. Our findings demonstrate that SERS intensities are determined by the thermodynamic adsorption behaviors of neonicotinoid molecules transitioning from aqueous phases to gold nanoparticle (AuNP) surfaces. The dynamic ranges and limits of detection can be accurately predicted by classic adsorption isotherms.
本研究探讨了表面增强拉曼光谱(SERS)用于新烟碱类定量分析的理论基础。我们的研究结果表明,SERS强度取决于新烟碱类分子从水相转移到金纳米颗粒(AuNP)表面的热力学吸附行为。经典吸附等温线可以准确预测动态范围和检测限。
